i havent boosted to much yet, just been playing with the 10 psi (getting 21-22mpg while im at it) Turbo is much louder now, wistles like a turbo-desiel! Gotta fix my vam again today, it BROKE a support bracket i made (yes it was metal with screws!!) and it pulled the bolt outa of the bottom bracket aswell...which led to it poping the vam off when i let off of boost lastnight...PITB blow thru!
